1. Increase of biogas production by incorporating residual streams from agriculture
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : To expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. LÄS MER
2. Vilka aspekter finns det att beakta kring gödselseparering och dess transporter?
M1-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : I dagens jordbruk finns det en ojämn fördelning utav näringsämnena från den animaliska gödseln. De flesta djurgårdarna är belägna i skogs och mellanbygd där det oftast inte finns tillräckligt med spridningsareal. LÄS MER
3. Practical strategies for acidification of animal slurry in storage
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and EnvironmentSammanfattning : Animal slurry is a source of NH3 emissions which results in loss of N and decrease the nutritive value of slurry. Slurry stores in Sweden represents approximately 30% of total NH3 emissions from agricultural activities in the country. LÄS MER
4. Systematic Assessment of Straw as Potential Biogas Substrate in Co-digestion with Manure
Master-uppsats, Linköpings universitet/Industriell miljöteknik; Linköpings universitet/Tekniska högskolanSammanfattning : This work was carried out at Biogas Research Center (BRC) and the company Biogas in Vadstena. The aim was to systematically evaluate new substrates for biogas production. In particular, this case investigated the potential of straw in co-digestion with manure and slurry from pig, chicken and dairy. LÄS MER
5. Environmental impacts of alternative co-substrates for biogas production : a comparative life cycle assessment
Master-uppsats, SLU/Dept. of Urban and Rural DevelopmentSammanfattning : In recent years, the production of biogas from animal manure has gained increased attention in Denmark, as it has been identified as an important resource to reach the goal of a fossil free society by 2050. In addition, manure management with biogas production has been recognized as a viable way to reduce environmental impacts from animal production systems. LÄS MER
